摘要： SM valves 50FL, 50FR are in an open position which opens a line when electric power is OFF and are switched to a closed position when energized by a brake controller 30. These SM valves 50FL, 50FR are formed integrally with the pressure regulation valves (here, the closed position refers to the position (pressure regulation position) where the lines are opened when pressure applied from W/C 2FL, 2FR side is over a predetermined value and the SM valves function as pressure regulation valves). Also, restrictions 50FLS, 50FRS are provided across a switching region where the opening and closing of the SM valve 50FL, 50FR is executed in the M/C 234 side to apply pressure between the restrictions 50FLS, 50FRS and the switching region. In this way, aeration which occurs when high pressure fluid is returned to the M/C side is prevented and thus, vapor locks can be prevented.
摘要翻译： SM阀50FL，50FR处于打开位置，当电力关闭时打开一条线，并且当由制动控制器30通电时将其切换到关闭位置。这些SM阀50FL，50FR与压力调节阀（这里关闭位置是指当从W / C 2FL，2FR侧施加的压力超过预定值并且SM阀用作压力调节阀时线路打开的位置（压力调节位置）。此外，在M / C 234侧执行SM阀50FL，50FR的打开和关闭的切换区域设置限制50FLS，50FRS以施加限制50FLS，50FRS和切换区域之间的压力。以这种方式，防止高压流体返回到M / C侧时发生的曝气，因此可以防止气体锁定。
